Troubleshooting
If double clicks register when you intend a single click, look for repeated intervals that are too short to be intentional. Compare results with lighter and firmer presses to see whether bounce correlates with pressure. If it happens on multiple PCs, the mouse switch may be failing.
Pro tip
Clean around the switch area and try another USB port before assuming the switch is failing.
Common symptoms
- Double click timing too short
- Single click becomes double
- Switch bounce suspicion
Double click time is a practical check for switch bounce versus settings or macros. You usually notice it when folders open twice, a weapon fires unexpectedly, or drag-and-drop drops the item mid-drag. This page measures click events and the time between them, also called the click interval, so you can see what is happening instead of guessing.
Do a few normal single clicks in the test area, then try the same pattern with lighter pressure. If you see extra events with very short intervals that you did not intend, that often points to switch bounce, meaning the contact inside the button is chattering. If the results look clean but you still get unwanted doubles in apps, your OS double-click setting, driver software, or macros may be the real cause. Also watch for patterns: if doubles happen only when you click fast, settings may be too sensitive, but if they happen during slow single clicks, bounce is more likely.
To get a fair read from this double click time, keep your setup simple. Close auto-clickers, disable mouse macros temporarily, and test in a second browser tab if you suspect an extension is interfering. If you can, plug into a different USB port and repeat the same clicks, consistency matters more than a single run. A quick wipe around the button and a blast of air can also help if dust is causing intermittent behavior.
If the extra clicks follow you across different PCs or browsers, the hardware is the likely bottleneck and you may need repair or a switch swap. If the problem disappears after changing settings, you can keep using the mouse and just tune it. For more input checks, use the input hub at Input tests and return to the main tool page at mouse double click tool when you want to re-run the double click time after a change.
